Atelectasis

Definition

Atelectasis is a collapse of the air sacs in the lungs called alveoli. It may occur in a portion of the lung, or in the entire lung. Normally, oxygen enters the body through the lungs and is exchanged with carbon dioxide in the alveoli. The lungs expand and contract to create the exchange of these gases.

Atelectasis is not a disease, but a condition or sign that results from disease or abnormalities in the lungs.

Other tests may be needed to confirm or rule out the cause of the atelectasis.

Treatment

Treatment focuses on treating the underlying cause and maintaining enough air supply. The collapsed lung usually expands after the underlying cause has been corrected. Mild atelectasis often goes away on its own without treatment.

Treatments include:

Physical Therapy

The therapist uses different techniques to help clear mucus from the lung. You will be positioned so that gravity helps secretions flow out of the body. When resting in bed, lie on the unaffected side to promote drainage from the lung area that has collapsed. Moving around will also help clear your lungs.

Respiratory Therapy

Respiratory therapy may include any or all of the following:

Breathing masks or treatments to help keep your airways open

Incentive spirometry to help you learn to take deeper breaths

Suction to help remove secretions

A breathing machine, called a ventilator, if you are unable to breathe adequately on your own

Medication

Your doctor may recommend:

Medications to open the airways

Medications or therapy to treat the health condition that caused the collapse

Antibiotics to treat an infection

Oxygen, if you are having trouble breathing

Bronchoscopy

Bronchoscopy may be used to remove a foreign body or mucus that is blocking the airway.
